lSpecification of Letters EPatent.

Patented AugM., 1915.

To all whom it may concern Be it known that I, OSCAR E. Ci-rANEY, a j

citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, .have linvented certain vnew and useful Improvements in GaseHeaters, of which the following is a specification.

This invention relates to new and useful imp rovements in gas burning heaters or stoves and as its principal object aims to provide a heater the parts of which are arranged to attain a maximum air consuming capacity for the heater whereby Athe combustion of the gases is as nearly complete as possible and the thermal eiiciency is relatively high.

An additional object is to construct kthe heater with such regard to number, proportion and arrangement of parts thatv it may becheaply manufactured, will be durable and eflicient in its action, and wherein access to the interior of the heater may be easily had for cleaning purposes.

A further Objectis to so construct the stove that it is provided with three independent aii chambers all of which are heated by a gas burner tube located in one of the chambers and serve to develop a relatively large volume of heated air which will, because of the particular .arrangement of the air chambers, continuously pass out into the room wherein the heater is used.

The above recited and other incidental objects of a similar nature, which will be hereinafter vmore specifically treated, are accomplislied by such means as are illustrated in the vaccompanying drawings, described in the following specification, and .then more particularly pointed out in the claims, which are appended hereto and vform a part of this application. l l

`With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention as itis reduced to practice, and throughout the several views of'which similar reference characters designate corresponding parts- Figure 1 is a Iperspective view of the heater; Fig. 2 is a vertical section taken medially through the heater as disclosed in Fig. 1; Fig?) is a top view; and Fig. l is a section on the line 4-4 of Fig. 2. p v.

In the embodiment of my invention illustrated in the .accompanying drawings and in '.Fig. .1 :thereof particularly, the heater consist'js essentially in a body casing 10 within which are positioned a removable casing 11 and a burner tube 12. The body casing 10 is preferably, although not necessarily, sub- '.stantially p rectangular in shape, and is formed from relatively light sheet metal. The side walls 13 and 14 of the casing are separately formed, and are connected at `their upper terminals by a topplate 15 vand at their' lower terminals by a bottom wall 16. The member 15 is in width considerably less than the side walls sothat a relatively large opening 17 is vdefined between the inner edge of the member 15 and the face plate 18 which connects the forward edges ofthe side walls adjacent' their upper terminals. The upper edges of the side walls and the member 18 are directed outwardly to form ledges or flanges 19 which serve as retaining members for the cover 15. As is shown particularly in Fig. 2, this cover plate is provided at its forward edge and at its side edges with inwardly directed flanges 15 which are engageable with (the yflanges 19 and serve to hold the cover against accidentall displacement. inasmuch as the .flanges 15 are freely engaged `with the flanges 19, the cover 15 may, of course, vbe removed for cleaning purposes or for permitting the removal of the inner casing 11. The member 18 is secured to the stove by bending its terminals at right angles and riveting them asv at 20 to the side walls. yThe front and rear longitudinal edges of each side wall 13 and 14 are bent at right angles and directed inwardly to form the vertical wings 21 and 22. To the vertical wings 22 of the side rwalls are secured, as by rivets or similarfastening means, the rear wall V.or back 22', which member is also formed of sheet metal. The members 21 of the two side walls are provided at their front edges with right angularl'y extending flanges 23 to which are riveted, as at 24, the edges of a substantially U-shaped partitioning member 25. kThis partitioning memberforms in connection with the side walls -13 and liliand rear wall 22- a substantially U-shaped air chamber A. The bottom wall 16 is provided Iwith a plurality vof air openings or vents 16 which admit the air into the chamber A at the bottom thereof. The manner in which the air is adapted to be heated and circulated into the room will be hereinafter' more fully discussed in that portion of the specification devoted to a description of the operation of the stove.

Through the rear wall 22l and traversing the air chamber A, is av stove pipe 26 the inner terminal of which is bent outwardly as at 27 to form a flange which may be riveted as at 28 to the inner face of the transversely extending wall 29 of the partition 25. On each side of the ange 27 there is at- `tached to the inner face of the wall29 and in vertical position thereon a pair of spacing webs or plates 30 which are substantially L- vshaped in cross section and arey secured by rivets or similar fastening devices 31. These members 30 are arranged 1n parallel spaced relation and serve to space the rear wall 32 of the removable casing 11 from Vthe wall 29 of the partitioning member. It is now to benoted that the removable casing 11 is substantially "rectangular and includes the rear-wall 32, front wall 33 and end walls 35 and 36. The member 11 is open both at thetop and bottom and is arranged with' its lower terminal in communication with a transverse slot 37 formed in the bottom wall 16 adjacent the rear edge thereof. I

Referring now to Fig. 2 it will be seen that air may enter the slot 37 and after passing through the casing 11 exit into the U-shaped air chamber A. The upper terminal of the casing 11 carries a closure plate 38 which is in length approximately equa-l to thedistance between the side walls of the member 25 and is of a width equal to the distance between the member 18 and the upper edge of the wall 29. The member 38 is fixed with respect to the upper terminal of the casing 11 and is adapted to be removed from the heater or applied thereto as a part of the casing. It is now to be noted that the wall 29 is arranged diagonally with respect to the vertical aXis of the heater and that the width of the air chamber A lthus increases as it approaches the upper end of the heater.

The casing 11 is normally held in engagement against the spacing webs or plates 30 by means of apair of holding plates 39 and 40 which members are substantially L- shaped in cross section and are secured by rivets 41 to the side walls 42 and 43 of the partition 25. The lateral portions of these members 39 and 40 are arranged in parallel spaced relation to the member 29. Itwill thus be seen that the removable casing 11 is supported within the heater at anl acute angle to the vertical aXis thereof. The purpose for which this structure is deemed advisable will be hereinafter more fully eX- pla'ined. 55s lrlhfflf It is now to be observed that a v .1. fsecond U- shaped air chamber, designated by the letter B, is defined by the casing 11 in connection with themembers 39 and 40 and the partition 25. This air chamber B communicates with the combustionchamber C of the heater through openings 44 which are f formed between the upper edges of the members 39 and 40 and the closure plate 38. Vithin the combustion chamber C is secured the burner tube 12. This member 12 is formed from a sheet of metal rolled into annular form and' punched in a number of places to produce the apertures 45. The tube 12 is supported' by means of a transversely arranged bracket plate 46 in spaced relation to the bottom wall 16 as best shown in Figs. 1 and 2. A gas pipe 47 is extended through the bottom walll and leads into the `tube 12 for the obvious purpose of supplying gasthereto.

On the front wall 33 of the removablecasing are arranged a series of baffle plates k48. These members 48 are transversely curved Vand arearranged in transverse series, the inf'lldividual baflie plates of eachseries being frgoppositely disposed with respect yto the Aplates of the adjacent series as will be readily seen upon reference to, Fig. 1. A pair of baiile plates 49 similar to the members 48 are also carried byleach ofthe members 39 and 40. The baiileplates 48 and 49 maybe lisecured by any suitable fasteningy means,

rivets being preferably employed.` A hoodv indicatedat v`50 is formed on the lower edge of the member 18 and serves as will be hereinafter explained, to prevent the escape into the room ofl an undue proportion of the air heated within the combustion chamber C by the burning gases ofthe tube 12.

The heater may be properly supported above the floor by means of legs 51 so as to admit air into the air vents 16. At the upper terminals of the side walls 13 and 14 are formed anumber of air vents indicated at 53. e

The construction and arrangementfofthe Y `parts, ofthe heater' beingthus disclosed,y I

will now explain the mannerin which the air in the various air chambers is heated and circulated from the stove. A p

Then the burner tube 12 'is lighted the air contained withinthe combustion chamber C is,'of course, immediately heated to a relatively high( temperature. time the side walls 42 and 43 ofthe partitioning member 25 and the forward wall 33 of the removable casing 11, as well as the `holding plates 39 and 40, are heated to a considerable temperature. As a result of the heating of the members 42 and 43 the air within vthe chamber A is raisedinwtemperature, and inasmuch as air enters through At the Y same icc l the lower air `vents 16 it is obvious that there will bea continuous circulation of air upwardly through the.: chamber A with the result that heated air willconstantlyA issue from the air vents 53 into the room. Also the cold air entering through the slot 37 will, in passing upwardly through the removable casing ll, be heated and will circulate through the member 1l and into the chamber A at the upper terminal thereof. The heating of the air within the chamber A. and within the removable casing 1l is considerably supplemented by the heated air and unburned, gases which pass from the combustion chamber C through the openings 44 and into the chamber B. Thischamber B forms, as will now be obvious, the communicating passage between the combustion chamber C and the stove pipe 26. It should now be noted that the lower ends of the members 30 terminate a slight distance above the bottom wall 16 so that the products of combustion passing from the combustion chamber C through the openings 44 will be carried downwardly through the chamber B to the lower terminal thereof, and will then proceed upwardly through the space deiined by the members 30 and then o-utwardly through the pipe 26. Thus, while the unburned gases of combustion are safely conducted from the heater so as not to escape into the room, they are utilized in their exit to supplement the heating action of the burner in raising the temperature of the air within the removable casing 11 and the chamber A.

In concluding the description of my invention, I desire to direct particular attention to the fact that the heater is relatively simple in construction and may, therefore, be manufactured and sold at a relatively cheap price.

rThe baille plates above described serve to set up conflicting currents of air in the combustion chamber C so that the mixture of the gas and the air is more thorough, with the result that the combustion of the gases is as nearly complete as possible. These ballie plates also, by setting up conflicting currents, eifect a uniform distribution of heat within the combustion chamber.

lu reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most etlicient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of this invention, as defined in the appended claims.
